Recently, neuromodulation techniques based on the use of repetitive transcranial magnetic stimulation (rTMS) have been/nproposed as a non-invasive and efficient method to induce in vivo long-term potentiation (LTP)-like aftereffects. However,/nthe exact impact of rTMS-induced perturbations on the dynamics of neuronal population activity is not well understood./nHere, in two monkeys, we examine changes in the oscillatory activity of the sensorimotor cortex following an intermittent/ntheta burst stimulation (iTBS) protocol. We first probed iTBS modulatory effects by testing the iTBS-induced facilitation of/nsomatosensory evoked potentials (SEP). Then, we examined the frequency information of the electrocorticographic signal,/nobtained using a custom-made miniaturised multi-electrode array for electrocorticography, after real or sham iTBS. We/nobserved that iTBS induced facilitation of SEPs and influenced spectral components of the signal, in both animals. The latter/neffect was more prominent on the h band (4–8 Hz) and the high c band (55–90 Hz), de-potentiated and potentiated/nrespectively. We additionally found that the multi-electrode array uniformity of b (13–26 Hz) and high c bands were also/nafflicted by iTBS. Our study suggests that enhanced cortical excitability promoted by iTBS parallels a dynamic reorganisation/nof the interested neural network. The effect in the c band suggests a transient local modulation, possibly at the level of/nsynaptic strength in interneurons. The effect in the h band suggests the disruption of temporal coordination on larger/nspatial scales.
